LINK CONFIGURATION OPTIONS

A number of link options are incorporated in the evaluation
board and must be set for the required operating conditions
before using the board. The functions of these link options are
described in detail in Table 2.

SETUP CONDITIONS

Before applying power and signals to the evaluation board take
care to ensure that all link positions are set as required by the
Table 2. Link Functions
Link Name Option
LK1 This link selects the V
Position A selects the internal voltage source (5V_VDD) from the ADP3331.
Position B selects an external supply voltage (EXT_VDD).
LK2, LK4, These links connect 100 kΩ pull-down resistors from the input/output pins to AGND. When the link is
LK4-LK9, removed, the level of associated pins is determined by the configuration of the AD5592R.
LK20
LK3 This link selects the reference source for the AD5592R.
Position A selects the on-board 2.5 V reference as the reference source.
Position B selects an off-board voltage reference via the EXT_REF connector. Select this option if the
internal reference is to be used.

operating mode. The evaluation board operates in two different
modes—SDP-B controlled mode and standalone mode.
The Default Position column of Table 2 shows the default
positions in which the links are set when the evaluation board is
packaged. When the board is shipped, it is assumed that the
user intends to operate the evaluation board with the
board (SDP-B controlled mode).
